The Lowdown
Alright folks, Rusty here. Let's take a look at what’s cooking for Tarnos.
Right off the bat, I gotta be honest with you – it’s a slow start. The first few days are a write-off with poor conditions and onshore winds messing things up. You’re looking at a gap of about three days before anything worthwhile shows up.
The first real glimmer of hope arrives on Thursday, the 17th. The morning is the standout. We’ve got a clean 6ft swell from the northwest with a solid 11-second period, and the wind is absolutely glassy. That’s the kind of morning you set the alarm for. The combined energy is moderate (663), but the glass-off makes it all worthwhile. Tarnos is a beach/jetty setup, so when it's clean like this, it can be a lot of fun.
Then things get really interesting. Saturday the 19th morning is looking like the pick of the entire forecast. There's a good 7ft northwest groundswell rolling in, with a period of 13 seconds, and we’ve got clean offshore wind from the east at just 3 mph. This is serious wave energy – a reading of 1514, which is strong. This is excellent surf, but at over 7ft, it’s for experienced surfers only. If you’re an expert, get ready.
We get a bit of a lull after that, but the following week isn't a total loss. From Sunday the 20th through to Tuesday the 23rd, the mornings are looking tidy. Swell drops a bit, hovering around 4ft to 5ft from the northwest with that nice 12-second period, and we see those glassy conditions coming back with light offshore breezes. Great for a paddle.
After that, the swell fades significantly towards the end of the month. We get a little bump on Friday the 25th morning with 4ft and a long 12-second period from the northwest, and the wind is calm, so it’s worth a look, but the energy is low.
So, for the best on offer: Thursday the 17th morning for the glassy perfection, but the absolute standout is Saturday the 19th morning for the bigger, powerful, offshore groundswell. Get on it if you've got the skills.
Rusty.
